I’m a fan of Olight’s Baton 3 rechargeable LED flashlights. They can go from a very dim 0.5 lumens to 1500 lumens. I use the dim setting most—I often hike before dawn and half a lumen is just enough to light the trail in front of me. They’re expensive, around $70, but the features match my needs. I keep one in the car, one in a kitchen drawer, and one in a gear cabinet, for traveling.
I also have a rechargeable UV flashlight for hunting scorpions.
I might have enough to play a nighttime MLB or NFL game with, provided they are down low as some don’t have the reach of stadium lights. I have a bunch of head lamps & even two waist belt lamps for running. 3 bike lights (one on bars & one on helmet) for fall winter riding / running. I was gifted a beanie with a light in it & have a baseball-style hat with two watch-battery powered lights in the brim. I have a couple Guardian Angel lights, which are more to make me more visible but all have at least a single white LED & have various mounts for them. I have a couple RGB panels for photography & a couple of RBG wands, as well for light painting.
I was using one of the 500 wt bike lights to frame & focus a night photo shoot earlier this week.
I have oodles of flashlights around our house. The most common use for them is to find things on the floor. Drop the back of an earring? Hold the flashlight parallel to the floor and you can usually spot it very quickly. Whenever anything is lost or dropped, my first thought is to grab a flashlight.
In my experience, cell phones do not do as good a job for this purpose as a good quality dedicated flashlight.
I’ve also standardized on 18650 batts for my larger flashlights & headlamp. These batteries have a large capacity and can supply a lot of current for high power devices. I keep a bigger flashlight in the car, one each near the front and back doors of the house, one at my parents’ place, one with my travel and camping stuff. One charger does fine.
Of course, I also have some smaller lights around. One on my keychain, tied to my laptop bag, nightcase, several more scattered around the house.
For my EDC keychain, I was lucky to get (in 2016!) one of these nifty Jetbeam Mini-1 Cu lights. About the size of half a AA alkaline, it’s dual power, has an integrated USB Micro charging port & circuit (with tiny red/green status LED), and the cutest little 10180 battery inside. And the copper patina is great.
I have rechargeables as well, but they usually do duty in my remotes, mice, and other portable personal appliances. The typical LED flashlights I have tucked around the house use 1, 2, or 3 AAs. or 3 AAAs.
My neighbors know this, and it’s common to get late-night “Can I borrow a couple batteries?” visits. They don’t even bother calling first, as they know I’ll have some.
I grew up in a home where kids got toys that used C or D cells. My sibs and I would have to wait until the next family trip to Safeway to spend our allowance on crummy, big, over-priced carbon-zinc cells to get another 25 minutes of play-time.
Like Scarlett, I swore, “As God is my witness, I’ll never be batteryless again!”
Speaking of batteries, a year or two ago I went to Target, where I bought a pack of ten AA (or AAA) batteries for about ten bucks, mostly for remote controls. On the way home, I stopped at Costco, where a pack of forty AA (or AAA) batteries was fourteen dollars. I considered returning the smaller pack, but don’t use that size battery very often, so I didn’t.
I am an outlier here because we keep no flashlights readily available in the household (my state of Baden-Württemberg had low voltage level power outages of 12.68 minutes/year in 2021 - no statistics yet for 2022. The US had an average of 7 hours in 2021 according to eia.gov.)
I have a flashlight in my hiking backpack in the cellar and a power bank with integral flashlight in my work backpack in the study. In an emergency at night with a new moon I’d use my iPhone or the landline handset (which has a mode to light the display) to find the way to these flashlights.
